HR comparison

Mff73

What to think about this one?
TrailRunning session (almost flat), S9PP OHR, compared to SmartSensor linked to Locus on phone.
No tattoos, no that much hairs, not to much tighten.
Checked a few time with fingeronthewrist sensor to be sure,
Still not reliable yet for me. I don’t want to doubt each time.

@Mff73 if I were Suunto I would deactivate OHR for sports as long as it is like this for many of us. To much bad news imo. Also bad timing with Coros next level looking OHR…

@Mff73 Try switching arms if it helps or change watch position above wrist bone. Maybe ohr sensor will be tweaked thru updates.

The Apex2 and 2 pro are also not flawless.

@el2thek I personally think or hope both watches will do good with SW improvements. If you’re Suunto fan, change is no option

@Dušan-Ković I think it was said among comments it was a typo.

@dulko79 I just saw image and noticed S5PP…

Just a small comparison. I usually use Verity Sense as HR monitor for all activities, but today I wanted to try S9PP internal HR monitor. And it works bad…

Some Verity sense examples:

S9PP:

Hr is going allover the place. On Verity Sense you can make out all spikes. It blends individual spikes into single chunks.

@Dušan-Ković
are these direct comparison? it doesn’t look like.

Dušan Ković

@freeheeler Nope, different sessions, but S9PP graph is a lot noisier

Intervals today, as good as usual, under the rain and with colder temperatures even.

Lucky you.

A quick question to everyone with S9PP OHR experience.
I currently own the original S9B with stainless steel bezel and weight of 81g (by specification). The S9B OHR doesn’t work for me for anything other than slow walking. In case of running the HR simply jumps to extremely high and unrealistic values, regardless of how tight the strap is. I knew this buying the watch, so I’ve always used in combination with external HR strap and I’ve been fine with it. I believe the reason for this behavior is the large and top heavy dimensions of the S9B.
But the S9PP with it’s smaller weight and footprint looks like it could solve these issues. My question is - is there a noticeable difference in OHR accuracy between the steel and titanium S9PP models, since this is the only reason I would justify the price premium between the 2 versions?

Egika

@Ivan-Vasilev while you are right about the watch weight as a factor for OHR accuracy, the small difference between steel and titanium does not play a significant role.
All other factors (skin temp, watch position, armband tightness etc) play a way larger role.

@Ivan-Vasilev In my case, the OHR os the S9P is simliar to the S9B and I use it with a HR strap. I have discovered recently, howevere, that results are almost perfect if I wear the watch really tight, so it does not move at all when running. I have been checking recently and it seems to work as expected. But I need to get used to wear it so tight, TBH.

Other wrist (left) , surely same position, but this time result is good . But what I hate having a watch on left wrist

Just a good day or really my normal wrist is less prone to OHR ?
If I would have two S9PP to test together, I would have had some answers…

@Mff73 better blood flow in left hand

@Mff73

For me, It works better than s7 s9p or s5p. They show smoother line but this is filled with details.

Mff73

Thanks.
In this particular feature (OHR), the problem is to be sure it is working for ourself a’d then t being abl to trust it.
My last run tends to prove (once) the sensor can read my HR while running on left wrist. But for now, I have more bad readings than good ones.
I am maybe not compatible with this technology.
